Pretty much no. The ADSI specification was crippled from the start to specificly not compete with PBX offerings. It has one advantage of (very limited) programmability, but a phone like the SNOM has an open-source core. It also has the dubious value of being interchangeable with a regular analog phone, but that is about it. You will not get anything near the functionality and feature set of a SIP phone, and it has the further irritation that much of its signalling is both in-band and audible. It is too bad. If it were properly implemented, the concept behind ADSI is great. Unfortunately, Telcordia strikes again. -- Sean C.
